The gcd of two numbers is 17 and their lcm is 204. one of the numbers is 68. find the other number.

1 answer:

6 0

$x\cdot y=GCD(x,\ y)\cdot LCM(x,\ y)\\\\\text{We have}\\\\x=68,\ GCD=17,\ LCM=204.\\\\\text{Substitute:}\\\\68y=(17)(204)\\\\68y=3,468\qquad\text{divide both sides by 68}\\\\\boxed{y=51}\\\\Answer:\ \boxed{\text{The other number is 51.}}$

Answer:

the one for the finding the height is 3.3, the one with 7 as the height is 351.86, and the one with 3 as the height is 150.8

Step-by-step explanation:

h=V

πr2=41.5

π·22≈3.30247

V=πr2h=π·42·7≈351.85838

V=πr2h=π·42·3≈150.79645

If the function is y = 4.5x. Then the rate of change of the function expressed as a unit rate will be 4.5.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A bike rental company charges a fee per hour.

The charge, in dollars, is the same each hour.

The ordered pairs (3, 13.50) and (5, 22.50) represent the corresponding hours, x, and cost, y.

Then the linear equation is given as

$\begin{aligned} \rm y - 22.5 &= \rm \dfrac{22.5 - 13.5}{5 - 3} (x- 5)\\\\\rm y - 22.5 &= \rm 4.5x - 22.5\\\\\rm y &= \rm 4.5x \end$

Then the rate of change of the function expressed as a unit rate will be

$\rm \dfrac{dy}{dx} = \dfrac{d}{dx} (4.5x )\\\\\dfrac{dy}{dx} = 4.5$
